In 2009, when HD cameras weren't yet easily accessible and we weren't yet experiencing the social media craze, the band was watching the Metallica video recorded in a US prison at the end of one of their rehearsals. At that moment, the question arose: How would this be in Paraguay? This is how the idea of ​​holding a concert in the Tacumbu penitentiary was born. It took place on August 13, 2009 and this is the video of the concert held in one of the most dangerous prisons in South America.
